Abstract
Karyotype and morphology of mitotic chromosomes in five populations of medicinal plant Papaver dubium collected from various geographical locations of northwest of Iran were studied. Chromosome characteristics were measured from 10 complete metaphase cells using Micromeasure software. Results showed that P. dubium is a diploid species with 2n=2x=14 chromosomes. The karyotype consisted of seven pairs of submetacentric chromosomes with one pair of SAT chromosome chromosome 1 had a fair secondary constriction at the end of its short arm. Karyological characteristics of all materials studied were similar to each other; however, there were some variations on chromosome arm ratios and relative lengths among different populations. All of the populations placed on 3A class of Stebbin’s asymmetry categories
